Since soreserve(so, 256*1024, 256*1024) would always fail for the default value of sb_max, modify clnt_dg.c so that it uses the calculated values and checks for an error return from soreserve(). Also, add a check for error return from soreserve() to clnt_vc.c and change __rpc_get_t_size() to use sb_max_adj instead of the bogus maxsize == 256*1024.
